Small evap leak blues
« on: September 06, 2010, 10:17:26 pm »
So I've had my check engine light on forever and a day, with the small evap code. I have tried several gas caps, redid the lines in and out of the gas tank, and replaced the purge solenoid. All I see left to replace are the little special 90s and smaller hoses around the evap box, but can't seem to find a match at parts stores. Anyone have any luck finding these leaks themselves?

small evap leaks are a hard one to find with out proper diagnostic tools . it could be the sending unit on top of the tank. Maybe worth spending the money to have it checked out  instead of throwing parts at it.
Stupidity, if left untreated is self-correcting

That's what I thought it was going to come down to. I had a couple shops tell me that its not uncommon for a small evap not to show up on the smoke test and that's the only diagnostic tool they have. Just making sure I didn't miss something easy to do.
Thanks for the advise Dave!
